in nearly all living organisms‚ is the acid that carries genetic information. RNA- Ribonucleic acid (RNA)‚ is an acid that is present in all living cells‚ it’s main role is to act as messenger and carry instructions from DNA fro controlling the synthesis of proteins. What are Eukaryotic Cells and Eukaryotic Organisms? A eukaryotic cell is a cell that contains complex organelles like nuclei or mitochondria enclosed within a membrane and eukaryotic organisms are organisms that are made up of

5. 1. 1 Define species‚ habitat‚ population‚ community‚ ecosystem‚ and ecology. Species – A species is a group of organisms with similar characteristics‚ which can interbreed and produce viable‚ fertile offspring. Habitat – A habitat is the environment in which a species normally lives or the location of a living organism. Population – A population is a group of organisms of the same species‚ who live in the same area at the same time. Community – A community is a group of populations

However‚ there are a number of problems which are encountered with bioremediation as well. First‚ in order for organisms to successfully reduce pollutant levels‚ their population must

Development in the zebrafish is very fast compared to other vertebrate developmental model organisms. The embryos develop quickly in a transparent egg by making it possible to observe the entire process of vertebrate development. Organogenesis in zebrafish is rapid‚ and most organ primordia have formed by 24 hours of development. The 24-hour zebrafish

Macro environments relates to the larger forces that have an impact on society as a whole and not just on one or a few organizations. A single organization cannot usually have a significant impact on these forces and therefore can only adapt its marketing mix to account for the opportunities and threats that arise. One of the evidence about this is the article ’Optus hit with $5 million fine’ which was published in The Age of the July 8‚ 2011‚ it identify and explain the impacts and affects this
